We come to your yard, look at the slope of the lot, measure the space, and talk through your options. Within a few days you will have a written proposal that breaks out materials, labor, and the permit fee - so you know exactly what you are getting before you sign anything.
Once you approve the design and sign a contract, we handle the full permit process through Los Angeles County on your behalf. Construction typically takes 5 to 10 working days on-site. We manage all required county inspections, and we do not consider the job done until the final inspection passes and you walk through the finished project with us.
We hold a valid California Contractors State License Board (CSLB) license and carry general liability and workers compensation insurance on every project. Proof of insurance is available before any work begins.
We come to your property, look at the yard, and give you a written quote that breaks out every cost. There is no charge for the estimate and no pressure to sign. We respond to all requests within 1 business day.

"We had a steep slope in the backyard and no usable outdoor space. The team designed a multi-level deck that made the whole yard functional. They handled the LA County permit process from start to finish and kept us updated every step of the way. The deck was done in about a week once permits came through."
Marcus T., Walnut - Multi-level decks
"Our old wood deck had boards that were cracking and pulling away from the frame - we knew it was time to replace it. They pulled the permit, removed the old structure, and installed composite decking that looks completely different. The surface stays cool enough to walk on barefoot even in July."
Jennifer R., Diamond Bar - Composite deck installation
"We needed a privacy fence along the back of our property. They came out the same week I called, gave us a written quote within two days, and finished the fence in a single day. Clean work, no leftover debris, and the fence looks exactly like what we asked for."

Yes - any deck attached to your home or raised more than 30 inches off the ground requires a building permit in California. Skipping the permit can mean fines, forced removal, and real problems when you sell. The California Building Standards Commission sets the rules; your county enforces them.
Walnut averages over 280 sunny days per year. Untreated wood bleaches and cracks faster here than in cooler climates. Composite boards hold their color and resist UV damage with almost no maintenance. Wood costs less upfront but needs re-sealing every two to three years to stay looking good.
It does. Hillside lots are common in the San Gabriel Valley foothills, and elevated decks require taller posts, deeper footings, and more structural work. Costs are higher, but the result is a usable, level outdoor space where none existed before. A contractor with local hillside experience knows what is required.
If your neighborhood has an HOA, you typically need written approval from your architectural committee before filing for a county permit. HOA review can take two to four weeks on its own. Start there first. Missing this step can mean costly design changes after the permit has already been filed.
If the structural frame - posts, beams, and joists - is solid and the damage is limited to surface boards or railing, repair is often worth it. If the frame shows rot, the footings have shifted, or the deck was never permitted, replacement is usually the more cost-effective long-term decision. The{' '}North American Deck and Railing Association publishes free deck safety inspection guides to help homeowners assess their own decks.
Much of the San Gabriel Valley sits on clay soils that swell when wet and shrink when dry. This seasonal movement can shift deck footings over time if they are not dug deep enough. A contractor familiar with local soil conditions will design footings to account for this - protecting your deck from leaning or cracking after a wet winter.
Walnut Deck & Fence is a licensed and insured deck builder company based in Walnut, CA, serving 12 cities across the San Gabriel Valley since 2017.
We hold a valid contractor license issued by the California Contractors State License Board (CSLB) and carry general liability and workers compensation coverage on every project.
Since 2017, we have completed hundreds of deck, fence, pergola, and outdoor living projects across the region, working on everything from ground-level wood decks to complex multi-level structures on hillside lots.
Learn more about usIn California, almost every deck attached to the house or raised more than 30 inches off the ground requires a permit. A contractor who suggests skipping the permit is either uninformed or cutting corners. An unpermitted deck can delay a home sale, create insurance gaps, and may need to be torn out at your expense.
Go to cslb.ca.gov and search by license number or business name. The CSLB database shows whether the license is active, what classification it covers, and whether any complaints have been filed. This takes about 60 seconds and is the single most important check you can do before hiring.
A thorough estimate lists materials (species or brand of decking, framing lumber grade), labor costs, permit fees, and any demolition charges separately. It should also include a realistic timeline and explain who is responsible for scheduling inspections. Vague line items like 'misc. costs' are a signal to ask more questions.
For additional consumer protection guidance, the California Contractors State License Board publishes a free Homeowners Guide to Hiring a Contractor. If you have questions about your specific project, call us at (626) 517-0597 or send us a message.
Walnut is a small, predominantly residential city in the eastern San Gabriel Valley with around 29,000 residents. Most of the housing was built between the 1970s and 1990s during a sustained building boom that turned open hillside land into the planned suburban neighborhoods you see today. The city is served by the Walnut Valley Unified School District, one of the top-ranked school districts in California, which draws long-term families who tend to invest in their properties. For census data on the city, see the U.S. Census Bureau quick facts for Walnut.
The city sits in the foothills, and that terrain shapes the work we do. A lot of Walnut's homes were built on graded hillside lots where the backyard drops away from the house - leaving yards that look appealing from the window but are hard to actually use. That is the situation we help homeowners solve most often. The city is also close to Mount San Antonio College (Mt. SAC), one of the largest community colleges in California, which sits right on the border of Walnut and serves as a landmark nearly every local resident knows.
Homes here are also subject to Los Angeles County building and safety services, since Walnut contracts with the county rather than running its own building department. That means deck permits go through the county - a process we manage entirely on your behalf. Walnut also has a high owner-occupancy rate, with more than 80% of housing units owner-occupied according to census data. Homeowners here tend to stay long-term and take care of their properties, which is the kind of client we do our best work for.
